Piped Chocolate-Dipped Butter Cookies

Leave the butter out of the refrigerator until slightly softened, but not overly soft or warm.

Blend the softened butter and powdered sugar in a food processor until smooth and evenly combined.

Add the eggs and vanilla to the butter mixture, then process until fully incorporated and smooth.

Add the all-purpose flour and baking powder, then mix until a smooth, pipeable dough forms and holds its shape.

Using a piping bag fitted with a star tip, pipe the dough in zigzag shapes onto an ungreased baking sheet, leaving space between the cookies.

. Use the oven's bake setting.

. Use the broiler setting.

Gently melt the milk chocolate, stirring until completely smooth and fluid with no lumps. Add the vegetable oil to the melted chocolate and stir until the coating is smooth, evenly combined, and glossy.

Dip one end of each cookie into the chocolate coating or spoon it over the cookies, leaving some plain.

Arrange the plain and chocolate-coated cookies on a serving plate and serve with milk tea or another hot drink.
